Save time and avoid product damage when cutting through thicker boxes with Labelmaster’s Klever Koncept Utility Knives. These are lightweight, bright blue and made of disposable plastic. They come with a slightly larger, permanent steel blade that is perfect for cutting thick cardboard. Their larger, curved shape rests naturally in your hand, making them easier to hold. They are designed to expose more of the steel blade, which provides more cutting leverage while protecting fingers and hands. These also feature an innovative tape splitter that enables box tops to be split open while saving the blade. They measure 5 3/4 x 1 1/2 in., and their compact size makes them easy to store.
